SHUTTLE.

This invention relates to certain new and useful improvements in ashuttle, and more particularly to the eye for guiding the yarn,

and it has for a principal object to pro-,

vide an eye of plflIStl Cj material which will be long-lived andefiicient in use. i

Further, the invention resides ;in the pro-' vision of an eye which isreversibleand consequently capable for use either in a right Another aimof the invention is found inthe cooperation between the eye and theshuttle which permits of the eye being easily threaded without danger ofthe yarn becoming dislodged by reason of the fact that the drag of theyarn is such that the wood of the shuttle prevents the yarn from comingout of the eye.

In the drawings Figure 1 is a fragmentary top plan view of a shuttleembodying the present invention.

Fig. 2 is a side elevation thereof.

Fig. 3 is a transverse section on line 3-3 of Fig. 2, and

Fig. 4 is a detailed perspective of the eye.

Referring more in detail to the accompanying drawing the numeral 1designates the body of the shuttle having the threading slit 2 and thecommunicating delivery eye passage in which is disposed the guiding eye3. This eye is preferably made of porcelain as the life of this plasticis much longer than that of metal in this particular adaptation.

The eye is provided with a pair of peripheral seats 4 with either ofwhich is engaged the eye securing pin 5, one seat being engaged by thepin in a right hand shuttle and the other seat being engaged by said pinwhen the eye is employed in a left hand shuttle so that the eye isreversible and consequently, universally adaptable for both types ofshuttle.

Each end of the eye is countersunk or formed with a central concentricdepression 6 which has a lateral outlet over the edge of thecylindrically shaped body of the eye, the peripheral portion of the eyeconnectlng the Specification of Letters Patent.

outlets of the end' depressions also being depressed inwardly"from themajor periphery, as at 7. This peripheral depression 7 extends the fulllength of the eye body and substantially aquarter way around, the lowerlongitudinal edge being formed with a thread slot 8 which also extendsthe 'full length of the eye body and radially to the center. Inpractical use, the depressed'portions of the eye are preferably polishedor given aglazed 'finish to facilitate the drawof the thread thereoverwhen threading the eye, while the remaining surface of the body is leftin the rough finish as is depicted clearly in Fig. 4, which roughperiphery better grips the interior wall of the eye passage of theshuttle.

The eye is arrangedin the eye passage so that the upper edge of theperipheral depression 7 is immediately above the entrance of thethreading slit 2, this latter entering the eye passage substantiallymidway be tween the upper and lower sides thereof. The peripheraldepression therefore cooperates with the opposing inner wall of the eyepassage in forming a downwardly di rected extension of the threadingslit which merges into the radially thread slot 8, the latter beingdisposed vertically in the shuttle.

Being secured against displacement by the pin 5, the inner end of theeye abuts a raised portion or platform 9 of' wood, being an integralpart of and cut from the body of the shuttle, said platform being cutaway, as at 10, to receive the inner end of the eye whereby the latteris protected and housed by the platform. This platform extends above thelower opened side of the thread slot 8, as depicted in Fig. 3, andsupports the yarn in its travel from the bobbin to the eye so that theyarn is secured against passing out through the opened side of the slot8 and back into the threading slit 2. Having a central end depression 6in each end, the bottom of the depression is thereby spaced from theplatform to afford easy passage of the yarn into the thread slot of theeye during the threading operation, this being true in either mountingof the eye.

It will therefore be noted that the eye is reversible, actingefiiciently in either the right or lefthand shuttle. The glazed finishof the depressed portions of the eye facilitates the passage of the yarnthereover and between the peripheral depression and the threading slitopening thereinto above its wood of the shuttle. Through the particularmounting anddisposition of the eye the drag of the yarn is such that thewood of the shuttle will prevent the same from being accidentallydisplaced. An important feature resides in the formation of the eye fromporcelain which is very desirable as the life is much longer than if itwere made of metal, and since the eye is well protected by the body ofthe shuttle there is little danger of breaking the plastic body, theterm porcelain belng hereinused to include analogous substances as 1sobvious.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent isl. A shuttle having an eye passage, a

bottom, and a platform extending horizontally across the inner end ofthe eye passage and above the bottom of the latter for guiding thethread, and a thread-guiding eye arranged within the eye passage andformed with a vertical radial thread slot which communicates through itsperiphery with the 25 threading slit of the shuttle below the platformwhereby the latter serves as ameans forholding the thread up in thethread slot tion being concentric to the remainder of the periphery, theends of the slot flaring outwardly, said flared ends terminating shortof the circumference, thebody being glazed within said flared ends; 9 V".In testimony whereof I have signedjmy name to this specification inthe presence of two subscribing witnesses.
